MacBook Pro :: Blurry External Display With DVI/VGA Adapter?
Jul 29, 2008
I'm using an external display with my MacBook Pro, using the DVI/VGA adapter.
My problem is that the display is a little bit blurry. It's not awful, but for example the display of the MBP itself is very crisp and clear so that's what I'm judging it against. Looking at text on the external monitor, some of the letters are reasonably clear, some are a little bit out of focus, and occasionally there is a fairly clear line like on the vertical of a t or an l. I'm sure there is a pattern to this but I couldn't tell you what exactly.
I'm using a Samsung Syncmaster 940NW widescreen display (the cheapest one I could find!) I have the MBP closed and I'm using Bluetooth kbd and mouse.
I've noticed that none of the resolutions available on the external display match the resolutions available on the MBP. The default res of the MBP is 1440 x 900 - I can get close (1344 x 1008, 60 Hz) to this but it seems none of the options on the display is the same as the ones available on the MBP's own display. Is this the reason for the blurriness?
I can still do work even with it looking this way, but I wondered if there's anything I can do to improve it.

When I hook up an external monitor to the DVI output, and use both the macbook screen, and the external, the display on the external is blurry, and not very sharp. However, when I close the macbook, and run it in clamshell mode, the external becomes very clear, and crisp (like it should). I never use dual monitors, so this really isn't a problem, but want to know if its normal. 2007 Macbook Pro, 2.4, 4 gig ram. Gforce 8600M GT

I finally did it... After a lifetime of Windows I've leapt from the Dark Side and am LOVING OSX... the combination of Spaces and Expose alone will save me countless hours!
I just got the VGA adapter to connect my spangly new MBP to the large monitor I used to use for my PC (no DVI capability on the large monitor, Acer x223w). Now however, I'm getting a strange and inconsistent problem:
If I connect all the cables and then power up, both my large monitor and the MBP screen appear slightly but infuriatingly blurry (see screenshot, left-hand side). If I power up MBP without connecting my large monitor and then 'hotplug' it (connecting the cable while everything is turned on), the blurryness is mostly cured - see screenshot right-hand side. The screenshot is from the same monitor in the two different states.

I just purchased a 13" MacBook Pro. When I attempt to use a TV as an external display, I get a flickering blue screen on my MacBook, and absolutely NOTHING on the television. I am using a Moshi adapter that I purchased from the Apple Store. Despite HOURS on the phone with tech support, I can't get this to work. I know neither the adapter nor the cable are defective. Does anyone have a solution?

I have recently bought a 13" Macbook Pro and wanted to hook up an external display (an oldish acer 19"). I have a Mini Displayport to DVI adapter hooked up to a DVI -VGA adapter which leads to the display. I haven't got it to work yet. I have followed advice about closing the lid and using usb mouse and keyboard with no luck. The only thing that happens is that the screen on the laptop flashes blue for about a second after plugging in the Mini DisplayPort adapter.

I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...
I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.
Info:
MacBook Air (13-inch Mid 2012), Mavericks 10.9.4

I'm very disappointed in this app. For several reasons. A few of them are:
1. It randomly zooms in and out and moves around when you don't want it to.
2. When you try to go to places outside the country (like Nepal or Thailand), everything is blurry when you try to zoom in on any area.
3. When you click the "Zoom In" or "Zoom Out" button, it often zooms all the way in or out - instead of just one click level in or out.

Together with my MBP I also purchased a MiniDisplayPort to DVI to hook up my external monitor. The graphics on my laptop are really sharp, especially with the glossy screen. Yet, for some reason, the graphics on my Samsung-monitor are extremly blurry. Compared to the MBP my 22" Samsung 226 BW seems to be very unsharp and lacks colour.

I have a new Macbook Air 13", 4GB RAM, 2.13Ghz, 256GB SSD.
I'm connecting the Macbook with the Apple Mini Displayport to DVI connector to a DVI cable to a Dell 2407 monitor with a resolution of 1920x1200. The resulting image is blurry. The fonts are blurry and drop shadows on the screen flicker quite badly. The resolution on my Macbook is indeed set to 1920x1200 to match my Dell 2407.
Does anyone know what the problem could be? Is the problem with the Mini Displayport to DVI adapter?
I know for a fact that the Dell LCD and the DVI cable work fine with my Windows 7 box. I have tried two different DVI cables as well.

I have a macbook pro and when I connect it to my external ASUS VH226H, 1920x1080 22" moitor all the fonts except the ones that are part of the OS not in external software are really blurry and rubbish. I've used the following apps and it all looks terrible: Coda, Firefox, Safari, Adium, Adobe CS5. I've tried changing the font smoothing options via terminal and it has made no difference.

I'm going to University next September (hopefully), and I want to be able to play my PS3 on my Macbook display (instead of taking my massive TV).
And I'd also like to be able to connect my freeview box which is a RCA/Scart connection. My PS3 is also RCA/Scart.
So is there adapter of some sort which will let me do this?

just picked up my new 15" 2.66 MBP w/AGD.
Which Display adapter will work best?
The MiniDisplayport to VGA or
The MiniDisplayport to DVI.
My External Monitor has both inputs.
It's a 22" Widescreen Acer that I got for free.
It's had problems waking from sleep from my old PC, using a DVI cable, but works fine waking from sleep from my work PC notebook, using a VGA cable.. Not sure if this is the issue or not.
I just want the adapter for my MBP that will most likely have fewer issues.
What do you think?

I have a 6 year old PowerBook G4 12" (Model 6,1) hooked up to a 20" VGA display using the Apple Mini-DVI to VGA adapter that came with the computer. Perfect performance for several years. I now want to hook up my early 2008 Black MacBook Intel Core 2 Duo 2.2 GHz. (Model 3,1) to the same monitor. The "Mini-DVI" connector on the MacBook computer does not mate with my adapter! It is real close in size and shape, but is obviously a different connector design.
The MacBook manual says the display port is a "Mini-DVI". The older PowerBook manual also says it's display port is a "Mini-DVI." Apple's site implies that the two computers require the same adapter, but that is obviously wrong. Some of the product reviews say that the Apple information is wrong, but no one has posted the correct information (part number). Is there an adapter for the black MacBook to VGA? I've spent all afternoon searching (including here an MacRumors) for the real part number for an adapter. No luck. I have also tried several Apple phone numbers and the chat forum, all with no results. Does anyone know what I should order to adapt the MacBook display port to a VGA cable, and from where?

I am looking for recommendations on a good Mini Display Port HDMI Adapter for my Macbook Pro 2011 Sandy Bridge. I have gone through about 4 adapters in the past year due to the adapters become unresponsive after 2 or 3 months. I use my Macbook heavily on external monitors for my work (averaging 7 hours or more a day between various monitors).
Info:
MacBook Pro, Mac OS X (10.6.7), Preview no longer works.

for the last week or so my MBA has been showing a ~3 inch bar running vertically along the middle-left of the display. Until today, the area looked just like blurry pixels (some things like graphics would still appear, so I don't believe the problem is with the pixels themselves). Now the area has become a gray bar of pixels.

Despite its description, I hooked it up to my receiver and it does NOT pass audio through. I've been hunting around and all I've found so far is one Youtube video of a guy with an adapter that worked (in the sound section of the system preferences, it shows another option for output that I didn't have), but not what adapter it was.

I also looked about for this but couldn't find anything.Im currently using a 13" mac book (Which i love) But the monitor is sooo small for using programs like logic and reason ect at the same time. I need to use an external monitor for this. I know you can get an adapter for this but do you have to duel screen your laptop with the screen. OR (This is my question) Can you keep your macbook closed maybe on a shelf somewhere and still use your macbook with a keyboard/mouse and the external monitor?
